The Air Intake and Carburettor assemblies should work in perfect harmony, the air filter/intake allowing correctly filtered air to enter the carburettor with as little resistance to the flow of air as possible.
The carburettor then has to deliver the correct balance of fuel and air to the combustion chamber via the inlet port.
All sounds simple enough? Well yes, basically it is, so long as all the parts concerned are in good, undamaged condition without any excessive wear to the carburettor internals.
So, basically, close inspection of those vital areas is highly recommended with replacement of components where required.
